Method and device for recognition and arbitration of an input connection
Embodiments herein enable fast and easy interconnectivity among multimedia accessories including mobile devices and other devices. There is only limited space on mobile devices yet there are numerous input connectors. The standard TRRS audio jack is one such input that has and remains common, primarily because it is the accepted standard for audio input; namely, headphones and earpieces for listening purposes. Embodiments herein describe an intelligent switch to that audio jack that permits for additional backward and forward compatibility. It transparently allows a user to insert analog or digital audio devices, such as earphones, without the need to manually reconfigure device settings. The device herein automatically converts between input connector types using the same input convention present on their existing mobile devices. Other embodiments are disclosed.
1. A communication device, comprising: a touch sensitive screen display; a microphone; a speaker; a connection port; a memory; a processing unit coupled to the memory, wherein the processing unit performs operations comprising: assigning, upon detection of a connector type of an audio connector of an audio device communicatively linked to the device through the connection port, a data line to or from the audio device to a pin utilized for a Tip, Ring, Ring and Sleeve (TRRS) line connection in accordance with the connector type.
2. The device of claim 1 , wherein the operations further comprise detecting an audio configuration of the audio device by way of current and load sensing through an audio jack of the device.
3. The device of claim 2 , wherein the operations further comprise communicatively coupling the audio jack to the processing unit by utilizing the TRRS (Tip, Ring, Ring and Sleeve) line connection.
4. The device of claim 1 , wherein the operations further comprise recognizing a dynamic pin allocation on an audio jack of the audio device.
5. The device of claim 4 , wherein the operations further comprise arbitrating the dynamic pin allocation on the audio jack to accommodate a multimedia type of the audio device.
6. The device of claim 1 , wherein the operations further comprise reconfiguring the pin upon detection of a microphone signal.
7. The device of claim 1 , wherein the operations further comprise detecting the multimedia connection.
8. The device of claim 7 , wherein the operations further comprise providing connectivity support in response to insertion of the audio device into the device.
9. The device of claim 1 , wherein the operations further comprise detecting the multimedia connection via the audio connector, wherein the audio connector includes an identifier component inserted into an audio jack of the device.
10. The device of claim 1 , wherein the operations further comprise converting an individual line signal on an audio jack of the device.
11. The device of claim 1 , wherein the operations further comprise multiplexing the data line with another data line of another pin of the device.
12. The device of claim 1 , wherein the operations further comprise overriding a default TTRS (Tip, Ring, Ring and Sleeve) pin setting to establish the data line.
13. The device of claim 1 , wherein the operations further comprise implementing a protocol for communication of data, executing an application, or a combination thereof, when the audio device is connected to the device.
